COTTON-GIN LINT FLUE.

Application filed June 3, 1925.

My invention relates to certain new and useful improvements in cotton gun but flues.

In the operation of lint flues for gun batteries, difficulty has been experienced in preventing a whirling of the lint in the flue or a tendency to accumulate more on one side than on the other of the lint flue before being discharged into the condenser. Under such conditions what may be termed an unbalanced bat results which cannot be handled so satisfactorily as a bat of balanced size with respect to a longitudinal vertical plane through the center of the lint flue at the point of its discharge into the condenser. Various means have been employed for controlling the discharge of lint from the several gins of the battery into the lint flue so as to balance the lint in the flue, adjustable baffles or. deflectors being usually employed for this purpose,but there are many practical operating objections to these deflectors or baffles and I have conceived that the control and regulation of the flow of lint from the lint flue into the condenser can be best justable in such connection and having its discharge end disposed so as to direct the lint from such connection into any desired portion, of the lint flue, considered transversely thereof, so as to effect a balancing or equalization of the flow of lint into the condenser.

It is a particular advantage of my invention that the gin flue connections can enter the bottom of the lint flue, instead of the sides, thereby avoiding by transverse currents whirls or eddies in the lint. Moreover, my preferred arrangement permits the control to be eflected by the allocation of the lint from one gin, preferably the gin next to the condenser, where it will effect the desired balancing of the lint flow to the condenser.

My invention further contemplates novel and effective means for mounting the regulatingdeflector nozzle in the controlling gin flue connection with a part thereof exposed so that it can be'adjusted by hand Without interfering with the connection between the gin and lint flues. 1

My invention also comprises the'novel details of construction for the connection'between the gin and lint flues in which the regulating deflector nozzle works and with Serial N0. 34,723.

which is associated means for locking it in any desired ad ustment.

Myinvention also comprises the novel details of constructlon and arrangements of' the line 2-2 of Fig. 1, the dotted line SllOW-' ing the level of a balanced flow of lint therethrough and the arrows showing with reference to the extreme dotted positions of the deflector the various directions in which the lintfrom one of the gins may be directed by mean positions of the deflector to maintain the balanced flow through the lint flue.-

In'the embodiment of my invention illustrated, I show a cotton gin lint flue 1 which may be termed the trunk flue, having a plurality'of gin flue connections 2 and 2 leadmg thereto, one from each of the several gin units of a battery. The gins are omitted, as they are not necessary for an understandin ofthis invention. It will be noted that the gin flues 2 and 2 lead upwardly at an incline inthedirection of flow of lint in the trunk flue and are connected separately to the bottom of the trunk flue. Theoretically, these gin flues should deliver their lint so that it Would flow in the trunk flue in a balanced condition. with equal volume on each sideof a longitudinal vertical central plane through the trunk flue, but as a matter of fact, experience teaches that such a balanced flow of lint will not be found to detail exist when. the lint is discharged from the lint flue into the condenser, not shown. It is the purpose of my invention to utilize the output of lint from one or more gins, but generally the lint from the gin nearest the condenser will balance the flow of lint to the condenser, and to this end the gin flue 2 from this end gin has its discharge end telescoped into the cylindrical end 3 of the reg ulating deflector which has an angularly disposed nozzle 4. This deflecting nozzle, as shown in Figs. 3 and 4;, has its axis disposed at an obtuse angle to the axis of the end 3, and is cut away on a plane at an acute an.- gle toits axis, which angle corresponds to the angle of approach of the gin flue to the lint flue, so that when the nozzle is set in its intermediate position, its upper edge will lie in a horizontal plane substantially level with the bottom of the lint flue. In such position the nozzle will discharge its lint into the lint flue exactly like the other gin flues except that it will be diverted upwardly at a greater angle. The cylindrical end 3 of the deflector is received ina pipe or flue 5 which forms a coaxial enlarged continua tion of the gin flue 2 This flue 5 has a ring 6' interposed between it and the casing 2 and rivets"? rigidly connect these parts. The

deflector end 3 will fit snugly into the space.

thus provided between the fines 5 and 2 and is held in position by rings 8 and 9 riveted to its outer side. This arrangement is shown more fully in Fig. 7, and affords a closely fitted tightjoint which yet leaves the deflector 3 free to rotate about the end ofthe flue 2 An operating stud screw 10 is inserted through an elongated transverse slot 11 in the casing 5 and is screwed into the ring 8 which is fast on the nozzle end 3 and its out-- er end being exposed furnishes a tool grip by means oi which the nozzle end 3 can be engaged and adjusted. The screw will be engaged in one of a series of threaded holes 12 in the ring 8, which holes are equi-distant and spaced on centers less than the length of the slot 11 so that as the nozzle is moved the full length of the slot a new hole 12 appears to receive the stud screw and permit v of further adjustment.

Having assembled the deflecting nozzle in the manner described, the operator, through observance of the flow of lint through wind ows 13 in the trunk flue, can determine to which side of the trunk flue it is desired to deflect the balancing flow of lint through the ginconnection 2 and by easing up on set screw 10 and engaging it with a suitable tool the nozzle can be thereby rotated about the axis of the connection 2 until the deflecting nozzle 4 has its axis pointing in the direction which will deliver the balancing flow of lint where it willproduce a balanced flow in the trunk flue. When this balanced condition has been obtained the set screw 10 can be screwed in tight when it will bind 011 the casing or fixed pipe 5 and hold the nozzle in the desired adjusted position. For the full range of adjustment the screw may have to be transferred to a number of the threaded holes 12 in the nozzle ring 8. \Vhenever for any reason it appears that the bat is not entering the condenser inv balanced size this regulating deflector can be again adjusted until the balance is restored. It will be noted that all of the gin flue connections enter along the center at the bottom of the trunk flue and at an angle disposed in the direction of the flow of lint therethrough. I thus avoid any tendency of the entering blasts of lint laden air to produce whirls and eliminate the necessity of long guides or deflectors in the trunk flue.

It will be observed that the nozzle end 4 of the deflector is not reduced in cross-sectional area as the flow of linttherethrongh should not be in anywise restricted. WVhile l have shown only one of the gin flue conneetions provided with a balancing deflector, it is to be understood that as many of such deflectors may be employed as are required for balancing the flow of lint for the trunk flue.

Though I have described with great particularity the details of th'e embodiment of the invention herein shown, it is not to be construed that I am limited thereto, as changes in arrangement and substitution of equivalents may be made by those skilled in the artwithout departing from the invention as defined in the appended claims.

It is within the contemplation of 'my invention that the novel type of deflector shall be applied to the discharge end of any gin fine or lint flue where occasion exists for the deflection of the lint being discharged for the purpose of regulating a bat in the condenser.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is
